Clothes treatment apparatus

Abstract

(EN) Disclosed is a clothes treatment apparatus (100) including a cabinet (1) having an opening (11), a tub (2) having a tub through-hole (27) and a tub aperture (21) communicating with the opening (11), a drum (3) rotatably installed within the tub (2) and configured to store laundry therein, the drum (3) having a drum aperture communicating with the tub aperture (21), a drive unit (6) having a rotating shaft (65) inserted into the tub through-hole (27) to thereby be connected to the drum (3), the rotating shaft (65) being movable in a radial direction inside the tub through-hole (27), and a drive unit support device (71, 74, R, L) configured to support the drive unit (6) such that the drive unit (6) is movable in a radial direction with respect to the rear surface of the tub (2).

Description

TECHNICAL FIELD [0001]The present invention relates to a clothes treatment apparatus.BACKGROUND ART [0002]A conventional clothes treatment apparatus includes a cabinet defining an external appearance of the apparatus, a tub placed within the cabinet, a drum rotatably installed within the tub to wash laundry, and a motor, a rotating shaft of which penetrates the tub and is coupled to the drum to rotate the drum.[0003]The tub is supported within the cabinet using springs and dampers. The springs connect an inner ceiling surface of the cabinet and an upper end of the tub to each other, and the dampers connect an inner bottom surface of the cabinet and a lower end of the tub to each other.[0004]In particular, the dampers are coupled to both sides of the lower end of the tub via hinges, which reduces vibration that would otherwise be transmitted to the tub during rotation of the drum.[0005]More specifically, each damper includes a circular cylinder connected to either side of the lower e...

AI Technical Summary

Benefits of technology

The present invention provides a clothes treatment apparatus that can reduce vibration and noise caused by the rotation of a drum. It achieves this by using a bearing housing that can levitate through magnetic force, allowing the drum to move in a radial direction within the tub. This not only reduces vibration and noise but also maximizes the volume of the tub placed within a cabinet that provides limited space.

Problems solved by technology

However, the conventional clothes treatment apparatus is limited as to reduction of vibration despite installation of the dampers.

Vibration of the tub and vibration of the cabinet caused by rotation of the drum may be further increased if the drum is rotated in an unbalanced state in which dynamic balance of the drum is broken.

On the other hand, in the clothes treatment apparatus, a state in which dynamic balance is broken (i.e. an unbalanced state) is a state in which mass distribution of the laundry about the rotating shaft of the drum is not constant during rotation of the drum, which occurs when the laundry is not uniformly distributed within the drum.
